When should i change my PC's

9-12 months. 9 months would be ideal IMO to keep the color shift from being to bad. After 12 months the color shift usually grows exponentially and when/if they are changed the corals may not like it too much. Kinda a shock to be exposed to bright light all the sudden. If you've ever changed a PC that is over 12 months old you WILL see what I'm talking about when you compared a new bulbs brightness/color to the old one:o.

Yes, you could get away with 12 months, but you'd be better off doing it sooner. Bulbs with faded spectrum can cause algae to take off too. We should get a poll of when people change their lamps.
